about this tool
churn rate is one of the most important metrics for any subscription-based business or service. it tells you what percentage of your customers or users are leaving over a given period — and if that number is climbing, it’s usually a sign that something in your product, pricing, or customer experience needs attention. but before you can act on churn, you need to measure it accurately.
this free churn rate calculator makes that simple. enter your number of customers at the start of a period and the number who left during that period, and the tool calculates your churn rate instantly. no spreadsheet formulas needed, no manual calculations.
it’s useful for saas founders, subscription marketers, and customer success teams who track retention as a core business metric. keeping a regular eye on your churn rate — monthly, quarterly, or annually — helps you spot trends early and understand the impact that retention has on your long-term revenue. small reductions in churn compound significantly over time, so it’s worth measuring carefully.

faqs
churn rate is the percentage of customers who stopped using your product or service over a given period. it’s one of the most important metrics for subscription-based businesses and saas companies.
churn rate = (customers lost ÷ customers at start) × 100. so if you started with 1,000 customers and lost 50, your churn rate is 5%.
for saas businesses, a monthly churn rate below 2% is generally considered healthy. for enterprise products, even 0.5–1% monthly churn is a strong benchmark. anything above 5% monthly needs immediate attention.
monthly churn measures customers lost in a single month. annual churn compounds over 12 months — a 2% monthly churn translates to roughly 22% annual churn. always clarify which one you’re reporting.
